The Evertz 7707MRA-HD is a specialized, high-density multi-rate input card designed for integration into Evertz's modular frame systems, such as the 7700 series, to serve as a versatile interface for computer video, data, and KVM extension in broadcast, production, and professional AV environments. This card functions as a critical gateway, accepting high-resolution RGBHV (analog VGA), DVI-D (digital), and USB signals from source computers and converting them into a format suitable for routing, processing, and extension over fiber or coaxial cable within the facility's infrastructure. Its primary role is to enable the centralized control and management of multiple computer workstations located in equipment rooms, while allowing users in production control rooms, edit suites, or master control to interact with them remotely with near-zero latency. This separation of noisy, heat-generating hardware from the user environment is a cornerstone of modern, clean facility design.

The card's engineering focuses on preserving signal integrity across potentially long distances. It supports a wide range of input resolutions, from standard definition up to WUXGA and 1080p, ensuring compatibility with a vast array of graphics workstations, servers, and playback devices used in broadcast graphics, video servers, and monitoring applications. The integrated KVM functionality is a key differentiator; it not only captures the video signal but also extends the keyboard, mouse, and USB peripheral data, allowing an operator at a remote console to have full, real-time control of the source computer as if they were sitting directly in front of it. This is achieved through proprietary or low-latency extension technology that ensures responsive cursor movement and immediate system feedback, which is non-negotiable for live production and editing tasks.

Designed for reliability in 24/7 operational environments, the 7707MRA-HD card is built to the high standards of broadcast infrastructure equipment. It slides into a dedicated slot in a modular frame, receiving both power and control from the backplane. Configuration and management are typically handled through Evertz's overarching software control system, allowing for easy assignment of inputs to outputs and monitoring of card health. By consolidating the capture and extension of computer video and data signals into a single, rack-mountable unit, this option card provides broadcasters and large AV integrators with a scalable, reliable, and high-performance solution for building centralized and streamlined operation centers.
